A woman who lied about her credentials to obtain a nursing job in the Haverhill public schools and then endangered the well-being of two disabled children was sent to jail Friday, officials said.

Lisa Haney Bilodeau, 40, of Haverhill was sentenced to 2½ years in jail with 60 days to serve and the balance suspended, prosecutors said. She pleaded guilty in Salem Superior Court to charges including reckless endangerment of a child, forgery of a document, and falsely claiming to hold a school degree.

Her lawyer did not respond to inquiries seeking comment.

Essex District Attorney Jonathan W. Blodgett’s office said Bilodeau applied for a nursing job in August 2013 and was hired at the Dr. Paul Nettle Middle School after claiming to hold an associate’s degree in nursing.

During a routine audit in May 2014, school officials asked Bilodeau to provide a copy of her nursing license, and she produced a document that was a clear forgery, Blodgett’s office said in a statement.

Prosecutors said that when Bilodeau worked at the Nettle School, a girl with Down syndrome and diabetes needed medical attention after Bilodeau’s “improper administration of her daily insulin shots.’’

In another case, a nonverbal boy who has cerebral palsy suffered infections near his feeding tube, and his family reported “concern that [Bilodeau] was not licensed or trained to administer the narcotics,’’ the district attorney’s office said.

Bilodeau was taken into custody after Friday’s hearing. The balance of her 2½-year sentence will remain suspended for three years, according to Blodgett’s office. Once she is placed on probation, Bilodeau will need the court’s permission before getting another job in the medical field, the statement said.
